Needing advice about PSU Watts

[RafaSimpsons]

GPU - AMD Radeon HD 6870
CPU - INTEL CPU CORE i5-3450
RAM - Gskill DDR3 PC12800 Ripjaws 8GB (2x4GB)
MOBO - MSI B75A-G43
HDD - Western Digital Caviar Blue 500GB
DVD-RW - Samsung DVD-RW 22x Sata
Cooler Master Haf 912 Plus

Will this PSU http://pconpt.com/product_info.php?cPath=24_89_90&products_id=1957 be enough for these components and will it still be enough for future updates?

430W is a bit weak. Corsair has a PSU finder you can use as a rough guide:

(the page defaults to memory, switch to power supply finder)

I would probably opt for a 550W minimum with your current setup, higher if you're planning to OC and to cover potential future upgrades (ie second GPU, etc).

650 is a head start, if you want enough power to add a second GPU later on, a 650 watt is your best bet

I won't has a second GPU.
First, because the MOBO doesn't allow it.
Second, because I will play at a resolution of 1440x900
Third, I will just upgrade to better one. Perhaps 7950, I don't know.
I will opt for a 500w

I think I'll change the case to a Zalman Z9 plus because I'm on budget and the PSU will be a Thermaltake Smart Modular 550W 80 Plus.

Do you agree?

^The cx430 will be enough for that system, although for some peace of mind I would spring for the cx500. Thermaltake don't make very quality psu's.

You can use that 430W PSU. You'll be cutting it a bit close but it will work just fine. I was going to ask what you meant by "future updates" but if you aren't talking about a second GPU then its fine. Your system as planned will use less then 300W, and you have 336W available on the 12V rail. So its close but will work.

If you want more of a buffer or might add a "big" card someday then by all means get a bigger PSU. A 500 or 550 should have the power to run any single GPU card out there. I don't know if that Smart Modular 550W is a good PSU or not. I wasn't able to find any reviews on it.

When I mean future updates I mean switching the GPU for a better one or a new CPU.

Is the Zalman Z9 plus a good case for this build?

here is a good one.

Cases are a personal choice. I never suggest which case to use. Use whatever you want to look at for the next ??? years.

If you are likely to buy a bigger GPU or CPU, then upgrade the PSU to at least a 500. I personally feel that 650W is overkill so I wouldn't go any higher then that.
